Description

FIELD OF THE INVENTION

This invention relates generally to hardware and, in particular, to devices for locking and sealing the doors of railway cars, freight containers and vans, tank hatches, helper wheels for grain carriers, warehouses, warehouses, shops, stalls and other objects.

More specifically, the invention relates to monoblock locking and sealing devices (ZPU), in which a flexible element is used as a contactor, for example, a piece of cable and, in particular, to devices in which, when locking, it is possible to form two loops.

State of the art

Known monoblock locking and sealing device (Patent RU 2111329, E05B 39/02), in which the housing is equipped with a recess and two through holes for a flexible element - a cable. One end of the cable is rigidly fixed in the case, and the cable itself is placed in the through holes of the case with the possibility of forming two loops, the first of which is formed by the portion of the cable between its closure in the case and the second through hole and covers the eyes of the door locking assembly, and the second loop is located in the recess housing and is formed by a portion of the cable between two through holes. A cable shank is located in the recess of the housing.

The cable is rigidly fixed in the shank, and the shank itself is pressed into the stepped hole.

A monoblock cable seal is known (Eurasian patent No. 006864, E05B 39/02), comprising a housing, in the blind channel of which a cable end is fixed, a through longitudinal channel for accommodating a cable in it, and an inclined hole is made in the housing. In the latter there is a spring-loaded locking element for interacting with a cable, and it communicates with a longitudinal through channel. At the same time, an additional inclined hole is made parallel to the inclined hole, which is in communication with an additional through channel made parallel to the first through longitudinal channel. Between the channels, a transitional recess for connecting the cable is made, which is protected by side projections. Outside, the housing is covered with a high-strength plastic shell.

This technical solution is taken as a prototype.

The disadvantages of the known solutions include the relatively high complexity of their manufacture, associated with the need to drill two inclined holes in them to accommodate the springs and locking elements. In addition to the prototype should include a disadvantage associated with the increased size of the product due to the fact that the cable is fixed with a bend of 180 °.

The technical result of the invention is to remedy these disadvantages.

SUMMARY OF THE INVENTION

This technical result is achieved due to the fact that in a flexible locking and sealing device containing a body and a piece of rope, one end of which is passive, and the second free end, when locked, is sequentially drawn through two passage channels in the body with the formation of two loops, sections of which interact with two spring-loaded locking elements protruding from the inclined channel into the passage channels, while one of the loops covers the eyes of the locking unit, and the second laid in the recess of the housing between the passage channels, according to the invention, the locking elements are placed at opposite ends of the same spring and in the same inclined channel, while the latter and passage channels are made in the form of grooves, and the passive end of the rope segment is mounted by pre-pressed sleeve in a blind stepped groove that interacts with the shoulder of the groove of the step of greater depth, and the adjacent section is located in the step of the groove of lesser depth and leaves the housing.

And also the fact that the case is made in the form of a rectangular parallelepiped and composite, consisting of a casing made of a profile with a through rectangular hole and an insert rigidly fastened with it, mainly by means of local crimping.

And also the fact that the case is made open and equipped with a lid rigidly fastened with it.

As well as the fact that there is a place on the case for the control identification marking and locking scheme.

Below the invention is illustrated by way of example with the accompanying drawings.

Brief Description of the Drawings

- Figure 1 shows a General view of the proposed device;

- figure 2 is the same, left view;

- figure 3 is a section aa in figure 2;

- figure 4 is an embodiment of a housing with a cover;

- figure 5 - the device is in the closed state.

Preferred Embodiment

The flexible locking and sealing device comprises a housing 1 and a piece of rope 2, one end of which is passive 3, and the second free end 4, when locked, is sequentially drawn through two passage channels 5 and 6 in the housing 1 with the formation of two loops, sections of which interact with two spring-loaded locking elements 7 and 8, protruding from the inclined channel 9 into the passage channels.

In this case, one of the loops covers the eyes of the locking unit, and the second is located in the recess 10 of the housing between the through channels 5 and 6.

According to the invention, the locking elements 7 and 8 are placed on opposite ends of the same spring 11 and in the same slope of the channel 9. The last and through channels 5 and 6 are made in the form of grooves, and the passive end 3 of the rope mounted by means of a pre-pressed sleeve 12 in a blind stepped groove 13, interacting with the shoulder 14 of the groove of the step of greater depth 15, and the adjacent section is located in the groove step of the shallower depth 16 and leaves the housing 1.

It is preferable that the casing is made in the form of a rectangular parallelepiped and composite, consisting of a casing 17 made of a profile with a through rectangular hole 18 and an insert 19 rigidly fastened to it, mainly by means of local crimping 20.

In an embodiment, the housing is made open and provided with a lid 21 rigidly fastened to it, while fastening can be carried out both by rolling and welding.

A place is provided on the housing for verification identification marking and a locking circuit.

The device operates as follows.

The free end of the cable segment is passed through the eyes of the locking unit, after which it is successively pulled through the passage channel 5 with the formation of the minimum loop - the first loop 22 and passed through the channel 6 with the formation of the second loop, which should be located in the recess 10 of the housing. In this case, the loop sections located in the passage channels 5 and 6, after completion of pulling through the latter, are sequentially locked under the action of the spring 11 by the locking elements 7 and 8 in the corresponding passage channels 5 and 6. Moreover, the locking in them will be the same. When you try to force extraction of the rope segment from the passage channels 5 and 6, the locking elements 7 and 8 under the action of friction forces are pulled by a large amount from the inclined channel (groove) into the corresponding passage channels 5 and 6, with greater force acting on the corresponding sections of the rope segment, which they are located in.

In this case, the presence of the second loop requires additional effort necessary to extract the length of the rope from the body when attempting an unauthorized opening, and up to a value bordering on the rupture of the rope.

The placement of the locking elements at opposite ends of the same spring and in the same inclined channel with it allows to reduce the dimensions of the product. This also contributes to the sealing of the passive end of the segment of the rope.

And the implementation of the passage channels and the inclined channel in the form of grooves, instead of holes, as is done in the prototype, is more technologically and rationally, since they can be obtained in the manufacturing process of the body blank by pressing or casting. Similarly, a blind stepped groove for the passive end of the rope segment can be obtained.

The invention is technologically advanced in manufacture and allows to increase the degree of protection of the structure from criminal effects.
